Abstract

The adults and gall of the sexual generation of the oak gall wasp Disholcaspis quercusmamma (Walsh and Riley) (Hymenoptera: Cynipidae) are described and matched with the alternate asexual generation for the first time. We also provide notes on the taxonomy, life history, and mode of sex determination of these insects. Chalcidoid parasitoids reared from the sexual generation were Sycophila dubia (Walsh) (Eurytomidae), Torymus denticulatus Breland (Torymidae), Mesopolobus sp., and Pteromalus sp. (Pteromalidae). This rearing of T. denticulatus is a new record for Colorado and a new associate of D. quercusmamma.
